WITNE printing point. For this purpose, there may e provided a series ofdecimal tabulating keys 14, which are vprovided'with levers 15 pivotallymounted intermediate their ends as at 16, and underlying at their rearends a series of counter stops 17, shown in the form of plungers adaptedto be brought up into the path of movement oi a series of column stops18, adjustably mounted on a rack 19 carried by the carriage 5. Each ofthe plungers or counter stops 17 hasla cutout portion as at 20, to forma shelf for a universal lever 21, whereby when any one of the tabulatingkeys is actuated, this lever will be rocked. The lever 21 is connectedto draw down on a link 22, which is arranged to rock a lever 23 carryingat its forward end a roller 24, which bears on the under surface of asmooth portion of the rack bar 12, so that when any one of thetabulating keys is actuated, the rack 12 will be moved out of mesh withthe gear 11, ermitting the carriage 5 to run forward free y until theactuated counter stop 17 comes into the path of the carriage or col umnstop 18 next to the right of the nest of plungers 17. It will be seen bythis arrangement that any decimal place or letterspace in a given columncan be brought to the printing point by a manipulation of the propertabulating key 14. In addition to this selection of a particular letterspace in a given column it is often of value for quick work, to enablethe operator to select any particular column, riage so that thiscolumnwill come to the printing point. In this instance, certain of thesame tabulating keys which control the selection of any particularletter space in a given column, are used to control the selection of anycolumn. To accomplish this,

certain of thetabulatin keys indicated 'at 25, of which 4-there are our,shown in this instance corresponding to four columns to which it ispossible to jump, are utilized to control a column finding mechanism,.In order that the columns to which" these keys correspond may bereadily ascertained, there is provided an indicating plate 26 in closejuxtaposition thereto, indicatino' the several columns by numbers 1 ,to4. These keys 25, therefore, are bothfdecimal tabulating keys and columnfinding' keys.

For the puropse of changing the function of the keys 25 from decimaltabulating keys to column finding keys, there is provided a special'control keyf27, which is provided with a lever 28 pivoted intermediateits ends and having ajslotted connection with the pivot 16 of the levers15, so as to be capable of moving relative thereto Vat this oint. Therear' end of the lever 28 under ies a .plunger or thrust link 29, so asto raise it,

- thereby swinging a rocker or bell crank 30 about its pivot. Rocker 30hasvrearwardly .seeing andbring the car' extending arms 31 on which ismounted a shifting rod 32 extending through alined slots .33, providedin all of the plungers or counter stops 17 with the exception of theinitial plunger or counter stop which is specially indicated at 34. Bythis arrangement it will be seen that when the special p control key 27is actuated, rod 32 willdraw all but one of the plungers or counterstops 17 forward, so as to bring` their upper ends out of subjacentrelation with respect to the column stops 18, permittin the counterstops to move upwardly without coming into the path of any of the columnstops 18.

ln order to bring the initial counter stop 34 forward to an ineifectiveposition, there is pivotally connected to the rocker 30 a latch 35having an upstanding lug 36 ena pin 37 on the counter stop or plun- .ger34. The latch'35 moves with the rocker 30, so that it swings the initialcounter stop or plunger 34 to its ineffective position at the same timethat the other counter stops are swung out" of active relation withrespect tothe stops 18. The forward movement of the initial counter sto34 tensions a sprin 38 which is connecte thereto, so

that this spring will tend to. return the :downwardly to permit thecounter stop 34 to swing back to its rearward position. The lug 36 oi.the latch 35, however, is provided with an upwardly and rearwardlyinclined cam edge 44, so that the spring 38 will not only swin thecounter stop 34 rearwardly', but will a so bring it up into the path ofthe column stop 18fwhich'is moving toward it. The trip 39 is itselfactuated t-o depress the latch 35 by the column stops 18, of which isprovided with a shoulder 45. As will be seen by reference to Figs. 2 and3, the shoulders are of different lengths, in-

creasing inlength from left to right of the carriage; that is to say,the stops 18 have a graded obstructing effect which increases from leftto right of the carriage, so that the trip 39 can be swung from aposition out of coperation with all of the stops, to a position intocoperation -with any one of the stops, depending upon the extent of itsmovement in swinging.

To set the trip 39 so that it will be actuated by any certain one of thecolumn stops 18, there is provided a lever 46 (see Fig. l),

4which is located in sucha position that it each will befactuated byorly one of the plungers or counter stops 17, corresponding to thetabulating keys 25, when they-arein their ineffective position. Whenthese particular counter stops or plungers 17 are in their in effectiveposition, lugs 47 underlie the bote tom of the lever 46, so that whenany one of the counter stops corres onding to the -keys 25, is raisedthe lever-wi 1 also be raised an amount depending upon the distance-ofthe lug` on the raised counter stop from thepivot of the lever 46, andalso depending von a series of steps 48 provided on the en' gaging edgeof the lever 46. Lugs 47, how over, are spaced apart at their top edgeslfrom the body portion of the counter stops 17, so that when thesecounter stops 17 are 4in their eiiectiv'e positions, capable of engag`ing with the column stops 18, the cutout portions thus formed will be inregister with the lever 46, so that the counter stops can be raisedwithout affect-ing the lever. The lever 46when` raised against-thetension of the spring 41, which is also connected there to, engages acam edge 49 provided on the' trip 39, so that the trip'39 is swung tothe vleft (see Fig. 7 a variable amount aecordwords, the trip isprojected inwardly the least amount. to stop the carriage correfspending to the column located farthest to the right, to avoid the otherstops 18, and in successively increasing amounts to catch the successivestops and avoid those located in front thereof. The upper edge of thetrip 3S) is guided in a slot 50 which permits a vertical and swingingmovement of the trip 39, but prevents a movement in the direction of thelength of the carriage, so that a cam surface 51 on the trip, whenengaged hyone vm the stops 18, will act to depress the trip against thetension of the spring 41, so as to release the latch 35.

In the use of the device, if it is desired to position the carriage tobring any letter K space of a given column in opposition te the:printing point, the corresponding key 14, 25

is depressed, so that the associated counter stop 17 will be brought upinto the path of the carriage stop 18, which happens to be to the rightof the manipulated counter stop. lVhen it is desired to skip a number oicolumns, or in otherwords to ind `any particular column, the key 27 isfirst depressed and held in its depressed position until one eectiveposition.

of the keys 25 is depressed. The movement of the key 27 shifts all ofthe counter stops 17 to the ition shown in Fig. 5, where they are alrendered ineii'ective to interrupt the movement of the stops 18. Thecounter stop 34, however, -is only held forward by the latch 35, and thespring 38 is always tending to return the counter stop 34 tc its As soonas one of the keys 25 is actuated, it lifts the corresponding counterstop 17, so that' the lug 47 thereon which was ineffective when thecounter stops occupied their normal positiomwill now engage the lever 46to raise it such an amount as will bring the upper end of the trip 39into the path of movement of the shoulder 45 on the proper column stop18. The trip 39, however, will not be moved forx .ward far enough toengage the shoulders 45 rof -such ofthe column stops 18 as may belocated in advance of the proper column stop for a particular key 25depressed. -As soon as the column stop 418 engages the trip 39, it actsagainst the cam edge 51 to depress it, whereby the trip in turn,releases the latch 35, permitting the spring 38 to draw the counter stop34 rearwardly and upwardly along the cam edge 44, in time to bring thetop end of the counter stop in the path of movement ofI the particularcolumn stop 18 which depressed the trip 39. The keys 27 andQ can then bereleased, and the parts will assume a normal position with the counterstops 17 in a position capable of acting tolocate the carriage inaposition corresponding to any letter space in a gi'ven column.
